Buy RS3 Cannonball
Cannonballs are ammo for the dwarf multicannon in RuneScape 3. Load them into your cannon and it fires at nearby monsters on its own. Each cannonball can hit for up to 1,152 damage. This makes them a strong pick for training Ranged or clearing big groups of monsters fast. They can also be used as ammo for the barker toad familiar, which can hit even harder but fires much slower.
Cannonballs are used up when fired and cannot be picked back up. That means players go through a lot of them. Buying a stack saves hours of work, since making them by hand needs the Dwarf Cannon quest, level 35 Smithing, an ammo mould, and steel bars. Each bar only makes 4 cannonballs, so smithing a big supply takes a long time.
Cannonballs are stackable, so a huge pile takes up just one spot in your inventory or bank. They weigh nothing and are members-only. Players with level 85 Smithing can even upgrade them with meteorite dust to make meteorite cannonballs, which hit harder. Keep a big stock ready so your cannon never runs dry during slayer tasks or long training trips.
